Here’s some choices of modes for editing crontab files,
HarleyGorrell has written a crontab-mode.el (original page gone it seems, but get it from archive.org)
From the commentary:
- I want to keep my crontabs under rcs to keep a history of the file. Editing them with ‘crontab -e’ is rather cumbersome. My method is to keep the crontab as a file, under rcs, and check in the changes with ‘C-c C-c’ after editing.
- The remote systems are expected to share a filesystem. If they dont, modify crontab-shell or crontab-apply to suit your needs.
crontab-mode.el, includes an rsh to edit crontabs on remote machines,

crontab.el which comes with XEmacs. Works in Emacs too.
Save-buffer installs the crontab. Optionally keeps a copy in ~/.crontab too, if you don’t trust the crontab to look after it.
Errors from crontab resulting in the new content not stored don’t seem to be reported very well.
